Newbie Zoanthid question.

How long will a zoanthid survive without the actinic bulbs
Only under 12k metal halides?
Are actinic bulbs a must?
thanks

Actually actinic bulbs are only for appearances. The light spectrum closer 10k is what they use for photosynthesis. We add actinic to make it look nicer.

edit:

sorry, re-read the original post

for MH actinic's are great and pull the color out of coral. +1 for keeping them in

your halide is much more important than the t5 portion of the lights

AAAHH so angry sorry.. i just saw my little maniac crab pulling my small zoa colonie into his rock ,....wth
i caught the bugger Please take him i have two of them i dont trust them now i put them in my overflow for now if anyone wants..i just bought them today

back to topic first reef tank new system running for a month now with only live rock . so.. i decided to put some color in it.i beleive the cycle is done.all my readings are 0. and some green leafy stuff is growing on the rocks.so i went to the store and got a good deal on a very nice green zoa . my first coral.and i thought hey ill put a couple of crabs in too.. they are pretty cool... so..now i have a zoa in two pieces one still glued to the rock because the crab riped it.
my light is a giesmann 150 mhx2 and 4 54 actinic but im waiting on a wire to run the t5
well first newbie lesson no crabs.. at least i saw him

Ooh neat! I like crabs, what kind are they? But for the zoas they should be just fine under your lights, mine grow well under a single 250w halide bulb, I have a couple extra little zoa frags if you wanna trade em for the crabs
